GPS manpack antenna, in-line mount, L1, 42 mm, 1575.42 ± 10 MHz
The APX/GPS is a Mil-Spec GPS active receiving antenna. Instead of using separate GPS and VHF communication antennas, the APX/GPS is inserted between spring/
gooseneck and antenna whip on standard Comrod manpack antennas. The GPS antenna will not be affected by the use of full transmitting power on VHF.
A filter on the GPS coaxial cable prevents the VHF signal from being conducted to ground through the GPS cable.
